Discord用户审批机器人报错：无法导入InvalidArgument

问题详情 #

我正在开发一款用于Discord服务器的用户审批机器人，运行代码时触发导入错误，代码和报错信息如下：

机器人代码 #

import discord

    bot.add_view(Verify())

ImportError: cannot import name 'InvalidArgument' from 'discord' (C:\Users\negojha\AppData\Local\Programs\Python\Python311\Lib\site-packages\discord\__init__.py)

错误原因 #

discord_components是第三方组件库，仅兼容旧版discord.py（v1.x）。而当前安装的是discord.py v2.x，在这个版本中，InvalidArgument已被迁移到discord.errors模块下，不再直接从discord根模块导出，导致discord_components导入失败。另外，代码中已经使用了discord.py v2.x特有的Modal功能（旧版v1.x不支持），所以降级discord.py并非可行方案。

解决方案 #

直接改用discord.py v2.x内置的原生UI组件系统，完全移除discord_components依赖：

1. 删除代码中from discord_components import Button, DiscordComponents和DiscordComponents(bot)两行
2. 将原本用discord_components.Button的逻辑，替换成discord.py原生的discord.ui.Button，并通过自定义View类管理按钮和点击回调
3. 移除bot.wait_for("button_click")的监听逻辑，改用View类中的按钮回调函数处理点击事件

上面的修改后代码已实现上述调整，同时修复了原代码中的小问题（如user.avatar需加.url获取图片链接、简化字符串判断逻辑、移除冗余参数等）。
